I would definitely get the Legendary edition of Skyrim. It has a ton of bug fixes, which will also be loaded up in typical free game patches, but it also included the three DLC's, which are all pretty solid. From what I've read, the content is on a second disc, so you might just have to run the second disc to download the DLCs onto your harddrive. Plus, you won't have to shell out extra cash for the game, since it's all already there. If you pay to download them, it's freakin expensive. I think I shelled out like $40US, which is steep, buy you absolutely get your money's worth. Be warned though, that game will consume your soul (and time) without you realizing it. It cost me a relationship, but the girl was kinda shitty to begin with, which makes it even more awesome.

As for Dragon Age and Dragons Dogma, I highly recommend Dragon Age Origins, the Game of the Year, or complete edition with all the DLC's if possible. Dragon Age was done by the same people as Mass Effect, so I suggest playing ME1 and seeing how you like it before DA. Dragon Age 2 is largely meh.

Dragon's Dogma was on paper, for me, a great idea. However, it drove me absolutely insane that there was no means of fast travel from one point to another. You'd have to venture quite a ways, almost always through the same territory, fighting the same enemies in the same spots, as they'd regenerate, kill a guy, find an item, or something, then have to trek back through the same areas to deliver the item, only to have to go through ALLLL the land you went through to do the same thing. Apparently they added a limited means of fast travel in a DLC, but it wasn't worth the money to buy it. People seem to love the game though, but it was a giant pain in the ass to me.

The pawn system is pretty badass though. In the game, you get to make your own permanent assistant, or pawn, and you can travel with two additional, interchangable ones, either NPCs or another real life gamers created pawn. You can't control them, but you can pick them based on their class, weapons and skills their owner has picked for them. And people can use your pawn in the same manner. Depending on their level, players can pay you a small fee of gold to rent your pawn at whatever their current level is, and they can provide you with items if they're a good guy or found your pawn useful. It's a really cool system, just a shame that the game was mostly going from A to B, then to Z, through all of the previous points.
